Maximum Performance of Thermal Printhead
Abstract:There are two types of thermal printheads. One is a flat type which has the heater line situated on the ceramic substrate's flat surface. And the other is edge type printheads which have the heater line either on the corner edge or the edge (called “True Edge”) of the head. Both corner and True edge type printheads offer straight pass capability, while flat heads do not. Using corner edge capability, an extremely high speed printhead has been developed. This is a printhead for in-line date-code printers. It has a printing speed of more than 40 inches per second. Also, a new high speed printhead for ID card printers has been developed. It has a print speed of more that three inches per second, using dye sublimation ribbons. It is a True Edge type printhead.
Thus, performance of thermal printhead speeds are maximized by edge type heads. Construction of the printheads to achieve these high speeds will be introduced in this paper.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
